the smoothness of the surface basically. i.e. 1000 grit sandpaper would have 1000 particles of grit per cm or inch. 200 grit would be much rougher as the particals are bigger, as there are only 200 per unit of measurment. hope this helps
The simplest answer is that working to a standard means that anyone can read the drawing. If there is no standard the symbols used on the drawing (weld type and size, surface finish, even the dimensioning of the components) would vary from one drawing (or draughtsperson) to another and cause confusion. Engineering drawings use a large number of symbols to denote operations and instructions (which reduces the time taken to draw them and the size of "paper" they're drawn on). Imagine the potential problems if one person used a symbol to mean "weld" and another one used the same (or similar) symbol to mean "do not weld".

The abbreviation of Engg. means Engineering.

This means a scientific achievement, or hypothesis.
Drafting means actually drawing the drawing.

Surface support in drawing refers to the underlying structure or foundation that provides stability and durability to the drawing medium. It can involve the use of various materials like paper, canvas, or boards that are designed to enhance the drawing experience and preserve the artwork over time. The choice of surface support affects the texture, appearance, and overall quality of the finished piece. Proper surface support is essential for achieving desired effects and longevity in artworks.
The surface is the ground upon which the medium is applied. If you are painting with oils, you are likely using stretched canvas or masonite board as a surface. If you are drawing in pastels, your surface may be Canson paper.

ER Finish on silver refers to a specific type of surface finish that is achieved through electrochemical polishing or other finishing processes. "ER" typically stands for "Electrolytic Refining," which enhances the appearance and quality of the silver by creating a smooth, shiny surface with a reflective quality. This finish is often used in jewelry and silverware to improve both aesthetics and corrosion resistance.
Do you mean a drawing "pen?"
Drawing a spade or club.
Ah, a lovely question! "Sface" may refer to "surface," which is the area on which you are drawing. It's important to pay attention to the texture and details of the sface to create a beautiful piece of art. Just remember to enjoy the process and let your creativity flow onto the sface of your drawing.
Surface morphology refers to the study of the physical structure and characteristics of a surface, including its roughness, topography, and features at a micro or nanoscale level. It focuses on understanding the shape, texture, and properties of surfaces for various applications in science and engineering.
Surface smoothness is typically measured in Ra (Average Roughness) or RMS (Root Mean Square) for engineering applications. These measurements give an indication of the fine details of a surface profile and are expressed in micrometers or inches. The smaller the Ra or RMS value, the smoother the surface.
It means you can't look at it or you'll go catatonic Cute. Actually, it means that the entity that is being "referenced", usually a dimension, should NOT be inspected. It might be an overall length of the part. This might be a "cut length" for the machinist where the actual required dimension is shown elsewhere on the drawing.
